    I don't know the brand, but from your fault description, you can judge one or two, the door lock can't pop out, it should be the deadbolt can't pop out, right? There are two possibilities for this, one is that the lock body transmission is broken, or the deadbolt is stuck, causing the deadbolt not to pop out. Another possibility is that the lock cylinder is too tight, resulting in the spring in the lock body unable to drive the lock cylinder to rotate, resulting in the deadbolt not popping out.

    Solution: First of all, remove the lock cylinder as shown below, and see if the deadbolt can not be ejected (oblique tongue), if it can, it is the lock cylinder, if not, it is the lock body.

Use a pencil to draw on the deadbolt, or use oil (do not use cooking oil) to lubricate, if it is ineffective, you must remove the internal oil or replace the lock body.
